Angular momentum evolution in M67
Published online by Cambridge University Press: 26 May 2016
Abstract
We present nearly 70 new observations for M67 members at the main-sequence (MS), turn-off (TO) and post-turn-off (PTO) in addition to those already published in Melo, Pasquini & De Medeiros (2001). These additional v sin i measurements confirm that most of stars are experiencing a strong braking as they pass the turn-off. In contrast to our previous results, some spread in the v sin i is observed among the TO and PTO stars.
